How to choose a car compressor?

Having thought about the question whether he needs a car compressor, where to buy a device, and which one to choose, the owner of the iron horse must take into account a number of factors. In particular, membrane compressors are considered obsolete today, so it is recommended to give preference to a piston compressor. Below about how to choose a compressor for the car, we will tell you more.

Selection features

When choosing a compressor, you should not focus only on the swap time of the wheel, even if it is the main function of the device. In practice, the comfort of its use will be an equally important characteristic of the compressor, in particular, the ability to shut off automatically when the wheel is pumped to the required pressure. It also appreciates the accuracy of inflation and the “ability” of the compressor to report pressure to the owner. Helping the owner to choose a car compressor, the consultant will certainly indicate his equipment with a digital pressure gauge, which is much more accurate than a switch.Included with a good autocompressor sold, as a rule, accessories, including a flashlight.

Perhaps the main advantage of a piston autocompressor is its power. According to this characteristic, the vibration type compressor is significantly inferior to the piston type. Thus, only a piston unit will be suitable for inflating tires of considerable size. A reliable piston compressor can create a pressure of 8 atm. The electronics of such a compressor ensures its continuous operation for 20 minutes, whereas it will take a maximum of 4 minutes to inflate a standard tire. Compressors of the latest generations are low noise, their vibration is almost not felt.

Electronic manometer

Two words about the advantage of an electronic pressure gauge. It not only surpasses the analog one in accuracy, but is also equipped with a special “Auto-stop” system, when the owner of the car programs the required pressure level on the screen, the auto-compressor pumps the wheel to the set level and switches off independently. Thus, pumping up the wheel from hard and dirty work turns into a simple and easy exercise that does not require the constant presence of a person and is not dependent on environmental conditions.Whatever the weather, the car owner is only enough to set the desired level of pressure, after which he can safely climb into the car, because at the end of the device will turn off itself. Often intending to buy a compressor, a car fan chooses a unit of the PH 20-12 because it comes with a flashlight with a built-in light filter. In the event of an accident, such a lamp indicates an incident with a red light.

As you can see, manufacturers of modern automotive compressors are actively using the latest inventions from the world of electronics. Now the flat tire out of place will not turn into an unsolvable problem for you; you can eliminate it today simply and easily, without effort having achieved the necessary tire pressure.

The main components of the autocompressor are the piston, cylinder, electric motor and pressure gauge. A piston-type compressor has become widespread today, since the membrane device is often unable to provide the necessary inflation speed and maximum tire pressure. The membrane compressor is especially unreliable in winter, when at low temperatures the membrane loses elasticity and the compressor is simply unable to start work.

Choosing a car compressor

It would seem that identical piston compressors actually have significant design features. How to choose a car compressor? The greatest reliability and durability of work will be ensured by the compressor, on which the metal piston rod is mounted directly on the motor shaft. There are options when the connecting rod is connected to the shaft through adapters and plastic bushings. Such a device will be less reliable in operation, its service life is limited. Also ask when buying what ring is installed on the compressor piston, regular or teflon. The latter will provide your compressor with longer operation time and will not require replacement during the entire term of operation.

Performance

The tire of a modern car is maintained at a pressure of about 1.8 to 3 kg / cm.2. Accordingly, when choosing an autocompressor, special attention should be paid to its performance, taking into account the characteristics of your iron horse's tires. For example, if the compressor capacity is in the range of 30-40 liters per minute, it will easily cope with the tire of not only a domestic car, but also a bulky SUV, unless pumping a jeep wheel takes more time.It is useful to know that the autocompressor with a capacity of over 45 liters per minute is not connected via the standard cigarette lighter connector, but by connecting the clamps directly to the battery terminals. This cannot be considered a disadvantage, just the compressor of such power consumes much more electricity, and connecting it through the wiring of the car is just dangerous, it can cause a fire. The best models of compressors have a very useful automatic shutdown function in case of overheating of the case.

Additionally, the compressor package may include such a useful thing as a long twisted hose with a pressure gauge. Due to this, the compressor can be fixed permanently, which creates more comfortable conditions for its operation. As a rule, a convenient bag for storage is given to the product, as well as a set of additional nozzles, which expands the areas of use of the unit.
